Abstract

The invention discloses a manufacturing method for an aquatic artificial wetland capable of purifying water. The method comprises the following steps of: (1) arranging a frame body by using square tubes; (2) encircling the frame body by using screens; (3) arranging a floating body at the bottom of the inside of the frame body to ensure that the frame body can float on a water surface; (4) arranging a layer of mixture consisting of biochar and moss at the bottom of the frame body; (5) pacing a biochar layer on the layer of the mixture; (6) arranging an ecological nutrient soil layer on the biochar layer; and (7) growing plants on the ecological nutrient soil layer. The invention also aims to provide the artificial wetland which is manufactured by the manufacturing method for the artificial wetland. The aquatic comprehensive artificial wetland does not occupy land, is easy to manufacture, low in cost, and strong in purification capacity and has the effects of beautifying and greening water surfaces of lakes and rivers.

Description

A kind of aquatic artificial wetland purified water and manufacture method

Technical field

The present invention relates to the processing that water pollutes, specifically a kind of aquatic artificial wetland purified water and manufacture method.

Background technology

Water resources is the base substance that the mankind depend on for existence, and along with population growth and social economy's develop rapidly, the requirement of water sharply increases, and water resource pollution is also day by day serious.China is since the eighties in 20th century, and due to the development rapidly of economy and relatively lagging behind of environment protection, many lakes, reservoir have entered eutrophication, even serious eutrophic state.Body eutrophication is a kind of organic contamination type, because the nutritive substances such as too much nitrogen, phosphorus enter natural water body, worsens water quality.Apply the chemical fertilizer in farmland, generally approximately have half nitrogenous fertilizer not to be utilized, flow into underground water or lake, pond, a large amount of sanitary sewages also often make the water body overfertilization.Too much nutritive substance impels the plant plankton in waters, as the amount reproduction of blue-green algae, diatom and pasture and water, the whole water surface is covered by algae and forms " spray " sometimes, is deposited on the bottom after algae death, the a large amount of dissolved oxygens of microorganism decomposition and consumption, cause fish because of the large quantities of death of anoxic.Body eutrophication can accelerate the decline in lake, makes it to develop to paludification.The eutrophication water of ecological engineering technology improvement in recent years comes into one's own day by day, becomes gradually major technique.In multiple ecological engineering technology, the artificial swamp treatment effect is good, less investment, and expense is low, is easy to maintenance management, is to use at present maximum ecological engineering technologies both at home and abroad.But existing artificial swamp need take a large amount of land areas, application is subject to certain limitation.

Summary of the invention

The objective of the invention is for existing technical deficiency, a kind of not land occupation area, the movable aquatic artificial wetland purified water and manufacture method are provided.

Realize that the object of the invention technical scheme is:

A kind of manufacture method of the aquatic artificial wetland purified water, comprise the steps:

(1) by square tube, a long 2m-5m, wide 2m-5m, the framework of high 60cm-80 cm are set;

(2) surrounding of framework is fenced up with 250 purpose screen clothes;

(3) bottom of enclosing in framework arranges buoyancy aid, makes framework at water surface floating;

(4) a layer thickness being set in the bottom of framework is 10cm-30cm, the mixture layer be comprised of biomass char and liver moss;

(5) laying a layer thickness on the described mixture layer of step (4) is 5cm, the biomass char layer that granularity is 5mm-20 mm;

(6) set up the ecoalimental soil layer that a layer thickness is 25cm-40cm on the described biomass char layer of step (5);

(7) planting plants on the described ecoalimental soil layer of step (6).

Described buoyancy aid is connected to form by the plastics tubing of diameter 10cm-25cm.

The mixture layer of described biomass char and liver moss is by weight percentage: biomass char 50%-70%, liver moss 30%-50%.

Described ecoalimental soil layer is selected the matrix of patent No. ZL200710048385.9.

Another object of the present invention is to provide the artificial swamp of the manufacture method manufacture of the above-mentioned artificial swamp of a kind of use.

Biomass char in aquatic artificial wetland of the present invention has very high surfactivity, can allow a large amount of microorganisms multiply in its surface honeycomb gap, bryophyte mainly contains absorption moisture content, the desired nutritional compositions and the effect that is attached to other body surface of soil such as inorganic salt, both are heavy metal and the mineral substance in adsorbable water body all, can also provide good environment for microorganism in water and algae existence, procreation.Nitrogen in water can be absorbed by biomass char and bryophyte, and phosphorus is absorbed by microorganism, algae.Nitrogen, phosphorus that biomass char more can come up absorption effectively are stored in wherein, for plant-growth, need.The ecological nutrition soil of patent No. ZL200710048385.9 provides the nutrient of high-quality for plant, and plant, by the oxygen therapy effect of photosynthesis and stem, root, is supplied with the oxygen that the wetland scrubbing needs.The microbial film of root system of plant and filling surface has cleaning action.

Aquatic artificial wetland floatability of the present invention is on the water surface, inject artificial swamp under the dynamic action of water flow, each layer of filler of flowing through, holding back, adsorb, absorb, degrading with organic pollutant and phosphorus and nitrogen in removal water through filler, root system of plant microenvironment, through the screen cloth of water from framework purified, return in water, thereby form optimum ecological recycle system, realize the purification to water body.

Aquatic artificial wetland of the present invention is the land occupation area not, can move flexibly, and simple for production, cost is low, and detergent power is strong, can also play the effect of beautifying, afforesting to lake, river.
